Re: [Discuss-gnuradio] How to add c++ modules after gnuradio-3.2.2. binary installation?

[Yao Jack]

Hi,

   I reinstalled the system and now it worked.
  I have managed to run qa_howto.py successfully after binary installation
inside the gr-howto... directory.
  My new question is
  
  How can I add new functions and modules using c++ files based on
gnuradio-3.2.2 ? 
  
 For example, there are howto_square2.(h, cc) function in src/lib. I tried
to introduce 
howto_square3.(h, cc) by simply copying howto_square2.(h, cc), 
 and I modified the codes with correct names and classes. 

 I then modified makefile.am and howto.i in src/lib by  
 mimicking  declarations of howto_square2.(h, cc), and square2_ff and added
 declarations of howto_square3.(h, cc), and square3_ff.

 Finally I "make, make check". In "make check" step, the system gave error
below,

ImportError: /usr/lib/python2.6/dist-packages/gnuradio/_howto.so: undefined
symbol: _Z21howto_make_square3_ffv
FAIL: run_tests

 Could you help solve this problem or give me a general guideline? 
Thank you.

 Yao

Hi

  I installed gnuradio-3.2.2. Binary package in Ubuntu 9.04.  
 It was not flexible to include new c++ files 
 (I could not find bootstrap, configure.ac  files etc in usr/share/gnuradio
installation directory).

 I then downloaded gnuradio-3.2.2.tar.gz and
gr-howto-write-a-block-3.2.2.tar.gz files and unzipped them in my home
folder,
and 
 gr-howto-write-a-block-3.2.2 was included as a subdirectory in the
gnuradio-3.2.2 directory.

  I  used installation commands ./bootstrap, ./configure, make, sudo make
install
 in gnuradio-3.2.2 directory, and no error was reported. I then tried to run
file 
 qa_howto.py (after chmod +x qa* ) in directory
gr-howto-write-a-block-3.2.2/src/python, as follows:

 ./qa_howto.py

 Error was reported that "in import howto", "howto" module could not be
recognized.
 I tried many other means, including modifying makefile.am in several
directories,
 and 
 using installation ./bootstrap, ./configure, make, sudo make install
 in gr-howto-write-a-block-3.2.2 directory.  No error was reported.

 But still 
./qa_howto.py 
 could not work.
 
 Questions: 

1) How can I make this work? 
2) How can I add new functions and modules using c++ files based on
gnuradio-3.2.2 binary installation? 
 
Thank you.

 Jack
